4.2 The Ordered List

Also known as the Numbered List. It is very similar in structure
to the unordered list, except each list item has a number in front of it,
instead of a bullet. Also, the opening tag for the list is <OL> instead
of <UL>, and the closing tag is </OL> instead of </UL>. Modify
the code in section 4.1 by changing the tags <UL> to <OL> and </UL>
to </UL> and change the title to ordered list. Save the file as orlist.html.
